It's the non p38 buyers I'd be thinking about,
Devils advocate mode
somebody that's always wanted one then sees yours, thinks wow, right up to the 5 minute job, hmmm I don't know anything about it, is it a 5 minute job or is there something wrong with it that's going to cost thousands to fix
I don't know how to do it so I'm going to have to pay somebody etc etc
If you fix it so it's working properly them ammend the description to say you've fixed it I bet there's more interest
